Floor joint sealing for homes and businesses in South Mundham
Gaps along the bottom of skirting are common in new and older homes alike. Decorators’ caulk usually cracks where there’s movement, so we close it with a flexible sealant instead. We’re often asked to deal with open joints that fill with dirt and failed joint filler in concrete floors, on tiled floors, commercial floors and concrete floor joints.
Older homes in small places like South Mundham often have timber floors that move with the seasons, which is why skirting and threshold joints need a flexible sealant, not filler.
Your job is guaranteed for a year, as with all our work.

Leave it or put it right?
Open joints along wet floors let water into the subfloor and behind skirting. Dealing with it early keeps the repair to the joint. Where a wall is exposed, as many are in small places like South Mundham, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
Commercial jobs are quoted on the same basis as homes: the amount of work, how we reach it and what it needs, along with when we can work on site. Call for a quick quote and we’ll explain what it covers.

Thresholds
Two different floors meeting at a threshold move differently. A flexible sealant bridges them.

Is there any odour?
There can be a smell while the sealant cures, which fades as it sets. Opening a window helps.

That depends on the joint. High-level, external movement and fire-rated joints are professional jobs.
Where is Mr Mastic based?
We work from Crawley. We cover South Mundham and the rest of West Sussex, along with the rest of our area.
What causes gaps between the floor and skirting?
It’s normally the floor moving: timber drying in winter, floors settling, or caulk that can’t stretch. A flexible bead keeps up with the movement.

Letting agents often deal with us directly. Tell us the address, the job and how access works and we’ll quote.
When to call us in South Mundham
When a tiled floor has no movement joints, the grout takes the strain. Cracks often run straight along a line of joints, where a flexible joint should have been.
These are the problems we are asked about most:
- Dirt and water collecting in open floor joints
- Failed joint filler in concrete floors
- Worn sealant at door thresholds
- Rigid edge joints in tiled floors
Managing a site like North Mundham Primary School? Then floor and threshold joints in busy corridors wear quickly and are best resealed early.
What your quote should include
- How long to leave it before use
- Are they insured?
